Api - get topic

Hi everyone, i’m with a question with the api, get topic to be more precise.

i’m getting my post (using http://my-forum/t/id.json) without any metada or css that i have posted to the forum. And when i try to edit my forum from the browser i’m getting my metadata without problem.

my question is how i can get the same metadata that i’m receiving in the edit option.

Thanks
